Now that Robben has had some time with the rig, he decided to change a few of the capabilities and effects that he's using on the pedalboard. The changes include:

- Removing the Dumkudo (Robben still loves this pedal, but is finding that he rarely uses backline amplifiers which was his intention for using this pedal. My understanding is that he's going to use it loose on the floor when needed).

- Moving locations of the Arion "Landau Modified" SCH-1 Chorus pedal

- Moving Vertex Boost in place of the Dumkudo

- Adding a Custom Stereo A/B unit for the two reverb pedals (Robben was finding that it was too complicated to switch between his two reverbs quickly, and asked that I build a custom A/B unit that could switch between the two pedals with one footswitch and then an additional footswitch as a bypass for when reverb was not needed).

- Adding two output buffer voicings depending on the amp and cabinet combination that Robben is using. I have a toggle switch mounted on the left side of the interface to change the between a dark voicing that Robben prefers with the Dumble, and a warmer voicing that's more for backline/Blackface Fender-style amplifiers.

Here’s a BEFORE and AFTER of the original (pre-Vertex) pedalboard and the newest version:

INTERFACE

Passive Input (no buffer), Stereo Outputs (left and right) with Vertex Dual Output Buffers tweaked to Robben’s taste with two voicings (adjustable via toggle switch), isolation transformer on left output to prevent any grounding when using two amplifiers together, and a polarity switch to optimize sonic performance when using two amplifiers in a stereo set up.

There is also an additional 5-pin DIN to 5-pin XLR junction in the center of the interface to allow Robben’s Dumble to be switched from the pedalboard. The pedalboard side is all 5-pin DIN at both the switcher and interface, on the outboard side the interface is all 5-pin XLR so that any 5-pin XLR. The interface is wired to accept any 5-pin DIN or XLR and the configuration for the Dumble switching is all done inside of the interface so any “off the shelf” cable could be used in an emergency with the same orientation.
